Description

Technical Field

[0001] This invention relates to the technical field of equipment water replenishment, and more particularly to an automatic water replenishment filter electrode hot water boiler. Background Technology

[0002] An electrode hot water boiler in a thermal power plant is a boiler device that uses electrical energy as its energy source and converts electrical energy into heat energy using electrodes to provide hot water for the power plant. It mainly consists of electrodes, a water tank, and a control system. In thermal power plants, electricity generated by generators is typically used; a portion is used for power generation, and the remainder is converted into heat energy by the electrode hot water boiler to provide hot water. The electrode hot water boiler heats water to the required temperature through the resistance heating effect generated by the current passing through the electrodes. The heated water can be used for heating, industrial production processes, and other heat energy needs. The application of electrode hot water boilers in thermal power plants is characterized by high efficiency and environmental friendliness, effectively utilizing electrical energy, and is simple, safe, and reliable to operate.

[0003] Most electrode hot water boilers are equipped with automatic water supply systems. These systems monitor the boiler water level through level control devices and automatically replenish water when the level is too low. The system can automatically adjust the water supply as needed to maintain a suitable water level. However, this water replenishment method involves components such as sensors, valves, and controllers, which require regular maintenance. If malfunctions are not addressed promptly, problems such as excessive water supply, over-discharge, scale buildup, and corrosion can occur, which not only shorten the boiler's service life and increase costs but also pose safety hazards. Furthermore, in electrode hot water boilers in thermal power plants, water supply filtration is an important measure to help purify and protect the boiler system. The main purpose of water supply filtration is to remove impurities, particulate matter, and suspended solids from the water to prevent them from entering the boiler system and damaging the equipment. Existing water supply systems lack equipment for automatic filtration and discharge during the water replenishment process. Summary of the Invention

[0016] The beneficial effects of this invention are:

[0017] Cold water enters the connecting pipe through the water replenishment area, passes through the control water core, and then enters the reaction boiler from the drainage area. The first and second convex rings, along with the drain baffle and drain cylinder, seal the water supply area and drainage area, ensuring their independence. The control water core is sealed by a sealing plate, ensuring the airtightness of the drainage area. The boiler's internal space is directly connected to the drainage area, and the cold water pipe is directly connected to the water replenishment area. When the pressure inside the boiler is lower than the pressure inside the cold water pipe, the cold water pushes the control water core to move and rotate, separating the water replenishment hole from the sealing plate. At this time, cold water flows from the cold water pipe into the boiler for water replenishment. This process utilizes the principle of pressure balance to drive the control water core, greatly reducing safety hazards.

[0018] During the water replenishment process, dirt will gradually accumulate inside the filter cartridge, filtering and collecting impurities in the cold water, and finally discharging them through the drain pipe. The dirt itself can cause blockages, which in turn drives the filter cartridge to move, so the more dirt accumulates, the more is discharged. Attached Figure Description

[0036] Example 1

[0037] Reference Figure 1 and 2 This is the first embodiment of the present invention, which provides an automatic water replenishment filter electrode hot water boiler. The device includes a boiler unit 100, including a reaction boiler 101; a connecting unit 200, including a connecting pipe 201 and a drain pipe 202, wherein the connecting pipe 201 is disposed on the outer wall of the reaction boiler 101 and the drain pipe 202 is connected to the outer wall of the connecting pipe 201; and a control unit 300, including a control water core 301, a sealing plate 302, a positioning ring 303 and a cleaning rod 304, wherein the control water core 301, the sealing plate 302 and the positioning ring 303 are all disposed inside the connecting pipe 201, and the sealing plate 302 and the positioning ring 303 are disposed outside the control water core 301, and the cleaning rod 304 is disposed inside the drain pipe 202.

[0038] Among them, the reaction boiler 101 is existing technology and is a commonly used electrode hot water boiler in thermal power plants. It is used to heat the cold water discharged from the connecting pipe 201. The inlet of the connecting pipe 201 is connected to the cold water supply system pipeline.

[0039] The connecting pipe 201 is preferably made of carbon steel and has an anti-corrosion coating on its inner wall. The outlet of the connecting pipe 201 is fixed to the outer wall of the reaction boiler 101 by bolts and communicates with the internal space of the reaction boiler 101. In order to ensure the sealing, a sealing gasket can be added at the pipe connection.

[0040] The main components of the control water core 301, sealing plate 302, positioning ring 303, and cleaning rod 304 are all made of stainless steel to prevent rust and water pollution. The positioning ring 303 is rotatably embedded in the connecting pipe 201, serving to seal, assist rotation, and position. The control water core 301 is inserted into the connecting pipe 201 from the cold water inlet end and contacts the positioning ring 303. The sealing plate 302 can cooperate to cover the outlet hole of the control water core 301, ensuring the airtightness of the inlet and outlet ends inside the connecting pipe 201.

[0041] During use, the other end of the connecting pipe 201 is first connected to the cold water supply unit. The cold water is pressurized and sprayed out from the cold water supply unit, directly impacting the end of the control water core 301. The control water core 301 is pushed into the connecting pipe 201 by the force, first sliding horizontally and then rotating. During the rotation, the control water core 301 pushes the sealing plate 302 outward, causing it to expand outward and expose the water flow hole on the control water core 301.

[0042] Furthermore, water flows from the control water core 301 into the connecting pipe 201, and finally into the reaction boiler 101 until the water volume in the reaction boiler 101 reaches the required level. At this time, the pressure inside the reaction boiler 101 is adjusted to be the same as the pressure inside the cold water supply pipe through the pressure regulating valve installed on the reaction boiler 101 itself. At this time, the pressure on the left and right sides of the control water core 301 is balanced, and it is no longer pushed by the cold water. Under the action of the spring, it resets, and the sealing plate 302 re-seals the outer wall of the control water core 301.

[0043] Furthermore, after the hot water in the reaction boiler 101 is heated and discharged, the internal water volume and pressure decrease. At this time, the pressure on the left and right sides of the control water core 301 is unequal, and the cold water will impact the control water core 301 again, causing it to rotate and open the sealing plate 302, thus injecting water into the reaction boiler 101.

[0044] Furthermore, during the water flow process, the control water core 301 can also play a filtering role. Only after the water is filtered can it enter the reaction boiler 101. The dirt and impurities that are filtered out remain in the control water core 301. As the dirt and impurities gradually increase, they will eventually be discharged from the unblocking pipe 202. The cleaning rod 304 can ensure the unobstructed flow of the unblocking pipe 202.

[0045] Example 2

[0046] Reference Figures 1-4 and Figures 8-12This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the control water core 301 includes a blocking core 301a and a filter core 301b. The filter core 301b is slidably connected inside the blocking core 301a. The blocking core 301a and the filter core 301b are preferably cylindrical in shape, and the outer wall of the filter core 301b is attached to the inner wall of the blocking core 301a.

[0047] The sealing core 301a includes a hydrophobic baffle 301a-1 and a hydrophobic cylinder 301a-2. The hydrophobic cylinder 301a-2 is movably connected to one side of the hydrophobic baffle 301a-1. The hydrophobic baffle 301a-1 can fit snugly against the inner wall of the connecting pipe 201, facilitating the assembly and disassembly of the hydrophobic cylinder 301a-2 and the hydrophobic baffle 301a-1, and also facilitating the insertion of the filter element 301b into the hydrophobic cylinder 301a-2. A water passage hole 301a-2a and a sliding groove 301a-2b are provided on the outer wall of 1a-2. The water passage hole 301a-2a has a rectangular axial section, while the sliding groove 301a-2b has an isosceles trapezoidal axial section. The water passage hole 301a-2a is connected to the internal space of the drainage cylinder 301a-2, and the sliding groove 301a-2b is located between the water passage hole 301a-2a and the drainage baffle 301a-1.

[0048] A water jet hole 301a-1a is provided in the middle of the water-draining baffle 301a-1. At least one set of arc-shaped sliders 301a-1b are fixedly connected to the outer wall of the circumference. The cold water discharged from the cold water supply system will first impact the water-draining baffle 301a-1, causing the water-draining baffle 301a-1 to move under the impact force. Then the cold water enters the water-draining cylinder 301a-2 from the water jet hole 301a-1a. A first support column 301a-2c is fixedly connected in the middle of the inner wall of the closed end of the water-draining cylinder 301a-2 away from the water-draining baffle 301a-1. A drain hole 301a-2d is also provided on its outer wall. A first spring T1 is sleeved on the first support column 301a-2c. One end of the first spring T1 is connected to the water-draining baffle 301a-1.

[0049] The filter element 301b includes a filter cylinder 301b-1 and a filter plate 301b-2. The filter plate 301b-2 is fixedly connected to one end opening of the filter cylinder 301b-1, and the other end opening of the filter cylinder 301b-1 faces the hydrophobic baffle 301a-1. The filter plate 301b-2 has at least one set of filter holes 301b-2a evenly distributed on it. At least one set of blocking inclined blocks 301b-1a are fixedly connected to the inner circumferential wall of the filter cylinder 301b-1, and the blocking inclined blocks 301b-1a face the other end opening of the filter cylinder 301b-1. At least one set of threaded guide plates 301b-1b are also fixedly connected to the inner circumferential wall of the filter cylinder 301b-1. The threaded guide plates 301b-1b can change the flow direction of water in the hydrophobic cylinder 301a-2, making the water flow spiral.

[0050] A second support column 301b-2b is fixedly connected to the middle of the side of the filter plate 301b-2 away from the filter cylinder 301b-1. The first spring T1 can also be fitted onto the second support column 301b-2b and connected to the filter plate 301b-2. A rectangular hole 301b-1c is also provided on the side wall of the filter cylinder 301b-1, and the rectangular hole 301b-1c corresponds to the position of the drain hole 301a-2d.

[0051] The cleaning rod 304 includes a rod body 304a, a fixed sleeve 304b, a toggle sleeve 304c, and an L-shaped toggle rod 304d. The edge of the fixed sleeve 304b is connected to the inner wall of the drain pipe 202. The top of the rod body 304a is rounded, and a frustum 304a-1 is fixedly connected to the bottom. A sixth spring T6 is sleeved on the rod body 304a. One end of the sixth spring T6 is connected to the top of the frustum 304a-1, and the other end is connected to the bottom of the fixed sleeve 304b. The toggle sleeve 304c is fixedly sleeved on the outer wall of the rod body 304a near the water replenishment area C. The lateral end of the L-shaped toggle rod 304d is rotatably connected to the toggle sleeve 304c.

[0052] The inner wall of the unblocking pipe 202 is also provided with a groove 202a, and the horizontal end and the vertical end of the L-shaped lever 304d are movably connected to the groove 202a; the top of the lever 304a can extend from the unblocking pipe 202 into the connecting pipe 201.

[0053] The remaining structure is the same as that in Example 1.

[0054] During use, cold water enters from the inlet of the connecting pipe 201, impacts the condensate baffle 301a-1, and then enters the condensate cylinder 301a-2 from the spray hole 301a-1a. At this time, the filter cylinder 301b-1 and the filter plate 301b-2 are located in the area between the water passage hole 301a-2a and the condensate baffle 301a-1. The first spring T1 is in its original extended state. Under these circumstances, the cold water can only pass through the filter hole 301b-2a on the filter plate 301b-2 and continue to flow backward.

[0055] Furthermore, after being filtered by the filter plate 301b-2, the impurities in the cold water remain inside the filter cartridge 301b-1. As time goes by and the number of times the cold water flows through increases, the dirt and impurities inside the filter cartridge 301b-1 accumulate more and more, eventually clogging some of the filter holes 301b-2a. If the cold water wants to continue entering the drain cylinder 301a-2, it will encounter great resistance. This resistance will eventually be converted into a thrust on the filter cartridge 301b-1. The first spring T1 is compressed and contracted by the thrust, the filter cartridge 301b-1 moves, and the rectangular hole 301b-1c will gradually move to the position of the drain hole 301a-2d of the drain cylinder 301a-2.

[0056] Furthermore, as the drain hole 301a-2d of the drain cylinder 301a-2 gradually overlaps with the rectangular hole 301b-1c, dirt and impurities will enter the drain hole 301a-2d from the rectangular hole 301b-1c. Under the thrust of the cold water, the drain hole 301a-2d will eventually connect with the drain pipe 202, and the dirt and impurities will be discharged into the drain pipe 202.

[0057] Furthermore, before cold water is introduced, the rounded top of the rod 304a protrudes slightly from the drain pipe 202. After cold water is introduced, the drain pipe 202 is pushed by the water flow. During the slow movement, the closed end of the drain pipe 202 will contact the rounded top of the rod 304a. Under the action of the rounded surface, the rod 304a is squeezed downward. At this time, the sixth spring T6 is stretched, and the actuating sleeve 304c moves downward with the rod 304a. At this time, the connection between the horizontal and vertical ends of the L-shaped actuating rod 304d will move down into the groove 202a. After the rod 304a moves down slightly, it will stop and reach its limit. Under the action of the groove 202a, the L-shaped actuating rod 304d will first expand and then contract, agitating the dirt and impurities in the drain pipe 202 to unclog the drain pipe 202.

[0058] It should be noted that when the water supply is stopped, the drain cylinder 301a-2 will reset. At this time, the rectangular hole 301b-1c and the drain hole 301a-2d will also be disconnected from the drain pipe 202. The sixth spring T6 pushes the filter cylinder 301b-1 to reset, and the drain hole 301a-2d will be disconnected from the rectangular hole 301b-1c. Even if there is still dirt that has not been completely drained, it will continue to be sealed inside the filter cylinder 301b-1 and will not leak.

[0059] Example 3

[0060] Reference Figures 5-12 This is the third embodiment of the present invention, which differs from the second embodiment in that it further includes: the sealing plate 302 includes a lower pressure cover plate 302a, a crescent-shaped top block 302b, and a connecting block 302c; the lower pressure cover plate 302a has an arc-shaped structure, the connecting block 302c is fixedly connected to both ends of the outer arc of the lower pressure cover plate 302a, and the crescent-shaped top block 302b is fixedly connected to the middle of the inner wall of the lower pressure cover plate 302a; the crescent-shaped top block 302b can slide within the water passage holes 301a-2a, and the radial cross-section of the crescent-shaped top block 302b has two arc-shaped sides, with one side being longer than the other side, forming two crescent-shaped arc surfaces; the connecting block 302c has a sliding hole 302c-1.

[0061] The positioning ring 303 includes a rotating ring body 303a, a first positioning element 303b, and a second positioning element 303c. The first positioning element 303b and the second positioning element 303c are evenly and fixedly connected to at least one set on the inner circumferential wall of the rotating ring body 303a. The first positioning element 303b faces the axis of the rotating ring body 303a to facilitate engagement with the drainage cylinder 301a-2. The second positioning element 303c is parallel to the axis of the rotating ring body 303a to facilitate engagement with the connecting pipe 201.

[0062] The first positioning component 303b includes a first sliding post 303b-1, a triangular locking block 303b-2, and a second spring T2. One end of the first sliding post 303b-1 is fixedly connected to the inner wall of the rotating ring 303a, and the other end is slidably fitted with the triangular locking block 303b-2. The second spring T2 is fitted onto the first sliding post 303b-1, and its two ends are respectively connected to the inner wall of the rotating ring 303a and the triangular locking block 303b-2. The triangular locking block 303b-2 can slide in the sliding groove 301a-2b. The axial section of the triangular locking block 303b-2 is an isosceles triangle, and the inclination angle of its two sides is parallel to the two sides of the sliding groove 301a-2b.

[0063] The second positioning component 303c includes a base 303c-1, a second sliding column 303c-2, an arc-shaped locking component 303c-3, and a third spring T3. The base 303c-1 is fixedly connected to the inner wall of the rotating ring 303a between adjacent first sliding columns 303b-1, providing a force-bearing point for the entire second positioning component 303c. One end of the second sliding column 303c-2 is connected to the side wall of the base 303c-1, and the other end is slidably fitted with the arc-shaped locking component 303c-3, which is a rectangular block. The ends of the two slides along the length are rounded. The axis of the second slide column 303c-2 is parallel to the axis of the rotating ring 303a. The end of the second slide column 303c-2 with the arc-shaped clip 303c-3 is flush with the end of the rotating ring 303a. The third spring T3 is sleeved on the second slide column 303c-2. Its two ends are connected to the side wall of the base 303c-1 and the arc-shaped clip 303c-3. When the arc-shaped clip 303c-3 is squeezed, it drives the third spring T3 to squeeze and retract into the rotating ring 303a.

[0064] The connecting pipe 201 has openings at both ends, forming a water replenishment space A inside. A first convex ring 201a and a second convex ring 201b are fixedly connected to its inner wall. Both the first convex ring 201a and the second convex ring 201b are circular. A positioning area B is formed between the first convex ring 201a and the second convex ring 201b. The rotating ring 303a can be placed in the positioning area B and rotate within the positioning area B. A water replenishment area C is formed between the first convex ring 201a and the opening of the connecting pipe 201 near its end. A drainage area D is formed between the second convex ring 201b and the opening of the connecting pipe 201 near its end. The water replenishment area C is connected to the cold water supply system, and the drainage area D is connected to the internal space of the reaction boiler 101.

[0065] The first pressure gauge J1 and the second pressure gauge J2 are also connected to the side wall of the connecting pipe 201. The first pressure gauge J1 is connected to the water replenishment area C, and the second pressure gauge J2 and the unblocking pipe 202 are both connected to the drainage area D. The unblocking pipe 202 and the second pressure gauge J2 are opposite each other and located on the same plane.

[0066] Compared to Example 2, the first pressure gauge J1 and the second pressure gauge J2 are both existing technologies and are pressure measuring instruments. The first pressure gauge J1 can monitor the pressure in the water supply area C and the cold water pipe in real time, and the second pressure gauge J2 can monitor the pressure in the drainage area D and the boiler in real time.

[0067] When the hot water boiler heats the internal water, the pressure will increase. At this time, the pressure in the drainage zone D will be greater than that in the water replenishment zone C. Under the pressure, the sealing plate 302 will be more tightly attached to the drain pipe 301a-2, and there is no need to worry about the water in the hot water boiler flowing back into the cold water pipe from the water inlet 301a-2a.

[0068] Furthermore, when the water temperature inside the boiler reaches the required temperature, it is discharged. At this time, the pressure will drop. The more water is discharged, the lower the pressure will be. According to the above embodiment, before use, it is necessary to balance the pressure between the boiler and the cold water pipe. When the pressure inside the boiler is less than that in the cold water pipe, the cold water can push the control water core 301 to move, thereby opening the gap to add water to the boiler. The speed of adding water depends on the amount of water discharged from the boiler.

[0069] A leak-proof platform 201b-1 is fixedly connected to the inner wall of the connecting pipe 201 on the side opposite to the second pressure gauge J2 in the drainage area D, which facilitates the discharge of dirt and impurities. One end of the leak-proof platform 201b-1 is fixedly connected to the second convex ring 201b. A lower drain hole 201b-1a is opened in the middle of the leak-proof platform 201b-1. The unblocking pipe 202 is vertically connected to the lower drain hole 201b-1a. When the cleaning rod 304 starts to work, the drain hole 301a-2d is connected to the lower drain hole 201b-1a.

[0070] An auxiliary block 201c is uniformly and fixedly connected to the end of the drainage zone D away from the second convex ring 201b. The auxiliary block 201c and the second convex ring 201b are respectively provided with a first lifting hole 201c-1 and a second lifting hole 201b-2. The arc-shaped clip 303c-3 can be engaged in the second lifting hole 201b-2. The positions of the first lifting hole 201c-1 and the second lifting hole 201b-2 correspond one-to-one. A stabilizing column 201c-1a is also fixedly connected to the side wall of the first lifting hole 201c-1 and the second lifting hole 201b-2 away from the axial direction of the connecting pipe 201. A fourth spring T4 is sleeved on the stabilizing column 201c-1a. The sliding hole 302c-1 is slidably sleeved on the stabilizing column 201c-1a. When the sealing plate 302 is squeezed and lifted, the connecting block 302c moves up and down under the restriction of the stabilizing column 201c-1a.

[0071] The first convex ring 201a is vertically connected to a fifth spring T5 at one end of the water replenishment area C. The other end of the fifth spring T5 is connected to a movable push plate 201a-1, the size of which matches the inner diameter of the connecting pipe 201. The inner wall of the connecting pipe 201 in the water replenishment area C is also provided with a vertical slide groove 201d and a threaded slide groove 201e. The vertical slide groove 201d and the threaded slide groove 201e are connected and extend from the opening of the connecting pipe 201 to the end of the first convex ring 201a. The arc-shaped slider 301a-1b can slide in the vertical slide groove 201d and the threaded slide groove 201e. The length of the fifth spring T5 is the same as the axial length of the threaded slide groove 201e.

[0072] The remaining structure is the same as that in Example 2.

[0073] Combined with reference Figures 1-4 During use, initially, the water core 301 is slid into the connecting pipe 201 along the vertical slide groove 201d until the hydrophobic baffle 301a-1 contacts the moving push plate 201a-1. During this process, the hydrophobic cylinder 301a-2 first pushes the triangular locking block 303b-2 to retract, and then contacts the chamfered corner of the crescent top block 302b, causing the sealing plate 302 to expand outward as a whole. When the hydrophobic baffle 301a-1... When a-1 contacts the movable push plate 201a-1, the sliding groove 301a-2b just moves to the corresponding position of the triangular block 303b-2, and the crescent top block 302b can be inserted into the water hole 301a-2a. At this time, the lower cover plate 302a can completely seal and block the water hole 301a-2a, and at this time, the top arc of the cleaning rod 304a and the drain cylinder 301a-2 are just about to contact each other.

[0074] Furthermore, when water is injected into the boiler, the water flow discharged from the cold water pipe pushes the control water core 301 to continue rotating along the threaded sliding groove 201e and moving into the connecting pipe 201. The sliding groove 301a-2b on the drain cylinder 301a-2 gives torque to the triangular locking block 303b-2, causing the positioning ring 303 to rotate as a whole. During this process, the triangular locking block 303b-2 still slides in the sliding groove 301a-2b. Meanwhile, the edge of the water passage hole 301a-2a pushes the arc-shaped crescent edge of the crescent top block 302b, lifting the crescent top block 302b upward. At this time, the sealing plate 302 moves upward as a whole, and the connecting block 302c expands outward in the first lifting hole 201c-1 and the second lifting hole 201b-2 under the limitation of the stabilizing column 201c-1a.

[0075] It should be noted that at the beginning of the rotation of the connecting pipe 201, the drain hole 301a-2d and the rectangular hole 301b-1c on the sealing core 301a and the filter core 301b were misaligned with the lower drain hole 201b-1a on the leak-proof platform 201b-1, forming a certain angle. When the connecting pipe 201 rotated to its limit position, the lower drain hole 201b-1a just coincided with the drain hole 301a-2d and the rectangular hole 301b-1c.

[0076] The initial deflection angle of the drain hole 301a-2d and the rectangular hole 301b-1c will not be covered by the anti-leakage platform 201b-1. At this time, even if there is dirt in the filter element 301b, due to the deflection of the rectangular hole 301b-1c and the gravity of the dirt itself, the dirt will accumulate at the bottom of the filter element 301b and will not pour out from the deflected rectangular hole 301b-1c. Furthermore, at this time, the rectangular hole 301b-1c is also misaligned with the drain hole 301a-2d, so it will not enter the drain cylinder 301a-2, let alone the lower drain hole 201b-1a.

[0077] Furthermore, when the drain baffle 301a-1 is moved to its limit position and can no longer move, the crescent-shaped inclined surface of the crescent top block 302b is still in contact with the edge of the water passage hole 301a-2a. At this time, cold water continuously flows from the spray water hole 301a-1a into the drain cylinder 301a-2, and finally enters the connecting pipe 201 from the water passage hole 301a-2a, eventually reaching the inside of the boiler.

[0078] Furthermore, during the continuous drainage process, the positioning ring 303 is rotated, and the arc-shaped clip 303c-3 changes from its original state of being retracted into the rotating ring body 303a to extending out from the rotating ring body 303a and inserting into the second lifting hole 201b-2. At this time, the entire positioning ring 303 will be temporarily fixed on the second convex ring 201b.

[0079] Furthermore, when the pressure inside the boiler is balanced with that of the cold water pipe, the forces at both ends of the drain baffle 301a-1 are balanced. At this time, under the influence of the elastic force generated by its own reset, the fourth spring T4 presses down on the connecting block 302c and pushes the lower cover plate 302a. The fifth spring T5 will also push the moving push plate 201a-1 to reset, so that the drain baffle 301a-1 rotates and moves in the opposite direction to the starting point of the threaded slide groove 201e. During this process, the arc-shaped crescent sidewall of the crescent top block 302b pushes the edge of the water passage hole 301a-2a to help it rotate and reset. When the control water core 301 rotates and resets in the opposite direction, the two ends of the arc-shaped clamp 303c-3 will also retract into the rotating ring 303a along the second slide column 303c-2 due to the arc-shaped rounded corner treatment.

[0080] Furthermore, when the water core 301 is restored to its initial state, the lower cover plate 302a of the sealing plate 302 still completely seals and covers the water passage holes 301a-2a. At this time, the internal space of the boiler and the internal space of the cold water pipe are completely isolated under the sealing of the sealing plate 302.
